"We have gotten no reports of anyone else getting them, but quite frankly the people who may have gotten them aren't likely to report it," prosecutor Rachel Hutzel said Wednesday.

William Perry, 22, of Columbus, and Rosanne Wead, 20, of Piqua, each pleaded guilty Tuesday in Warren County Common Pleas Court to a count of trafficking in counterfeit controlled substances. A third person, Jerry Snowden, 27, of Piqua, pleaded guilty last month to a counterfeit substance charge. He was sentenced to 18 months in prison.

Wead was sentenced to six months in prison; Perry has not been sentenced.
